AUTOMOBILE-JACK.

Application filed April 9, 1921. Serial lilo. 459,952.

To all whom it may concern:

Be it known that I, VAN V. Gnarls, a citizen of the United States of America, and resident of Follansbee, county of Brooke, and State of West Virginia, have invented certain new and useful Improvements in Automobile-Jacks, of which the following is a specification.

This invention relates broadly to lifting jacks, and it has for its object to provide a simple quick-acting form of jack designed for automobile use and which is particularly adapted to be employed in lifting cars of light weight.

A further object is to provide a jack of the character mentioned which provides for effecting elevation to the full limit of which it is capable by a single elevating movement of the operating lever.

With these and other objects in view, the invention resides in the features of construction, arrangement of parts and combinations of elements which will hereinafter be fully described, reference being had to the accompanying drawings, in which ,Figure 1 is a sectional elevation of the invention; I

Fig. 2 is a side elevation showing the movable standard member in an intermediate lifting position; and

Figs. 3 and 4 are front and rear elevations, respectively.

The invention comprises a standard composed of two sections 1 and 2 having hinged connection, interfitting lugs 3 and 4 carried on the front faces of said sections being con nected by a pivot pin 5. The lower section 1 is stationary on a base 6, while the upper section 2 is ,adapted for movement on said pivot pin to and from its normal position in which it seats upon the section 1 in vertical alinement with the latter. In its forward swung position the upper section 2 has its head disposed on a lower level than in the upright position thereof; consequently. a car axle or other object beneath which the head of said section 2 is introduced may be elevated on the jack to the level occupied by said head when said section 2 is in upright position. Carried on the rear portion of the under side of the upper section 2 is a downwardly and forwardly extending rack bar 7 of arcuately curved form, which is movable with said section 2 as the latter is swung to and from its normal upright position, said rack-bar being-received in :a channel or passage 8 provided-therefor in the lower section 1. Arranged to cooperate with said rack-bar is a dog or pawl 9, the same being mounted in said passage 8 upon a pivot pin 10 and occupying a downwardly and forwardly inclined position for engaging teeth formed on said rack-bar, whereby chance movement of the section2 ina for ward direction is prevented.

Loosely mounted intermediate its ends upon pin 11 carried by bearing lugs 12 formed on the rear face of the upper stand.

ard section 2 is an operating lever 18flVhen in operative position said lever has its init to said position, the lever is slipped laterally on its pivot pin 11 until its inner end enters a vertically elongated side chamber 14*, whereupon the lever swings unobstructedly to its vertical position due to the absence from said side chamber of any part corresponding to the shoulder 15.

From the foregoing it will be apparent that I provide a jack which may be advantageously employed for lifting the axles.

of light-weight automobiles and the like throughout short distances by a single elevating movement of the operating lever.

What is claimed is- 1. An automobile jack comprising a standard composed of hinged sections, the lower section having a passage therein, a curved rack-bar carried by the upper section and movable through said passage with rocking movement of said upper section, a. pawl arranged to cooperate with said rack-bar, and an operating lever carried by said upper section. a

2. An automobile jack comprising a standard composed of two sections, one superposed on the other, a pivotal connection between said sections permitting the upper section to be rocked to'and from upright seating relation to the lower section, an arcuately curved rack-bar carried by one of said sections, a pawl carried by.the other section for engaging'the teeth of said rack-bar to limit the forward rocking movement of the upper section, and an operating lever carried by said upper section. V r

3. An automobile jack comprising a standard composed of two sections, one superposed on the other, a pivotal connection between said sections permitting the upper section to be rocked to and from upright seating relation to the lower section, an arouately curved rack-bar carried by one. of said sections, a pawl carried bythe other section for engaging the teeth of said rack-bar to limit the forwardrooking movement of the upper section, the upper section having an operating chamber in the rear part thereof with an overlying shoulder and having a communicating side chamber of vertically elongated form, an operating lever pivoted intermediate its ends on said upper section and having its inner end received in said section havin operating chamber in underlying abutting relation to said shoulder, said lever being laterally shiftable into said side chamber to permit unobstructed movement of said lever to vertical inoperative position.

4. An automobile jack comprising a standard composed of hinged sections, the lower a passage therein, a curved rack-bar carriedby the upper section and movable through said passage with rocking movement of said upper section, a pawl arranged to cooperate with said rack-bar, an operating lever pivotally mounted on said upper section and laterally shiftable, said lever being operatively disposed when in one position and being movable to a vertically disposed inoperative position when shifted laterally from the first-mentioned position.

a In testimony whereof, I afiiX my signature in presence of two subscribing witnesses.
